Hello guys I'm sending a prospective email to a venue, regarding an event that I want to organise. But I'm unsure of my approach in firstly asking the question (it sounds out of place), and just the general tone of the email. The email is as follows:-

To Whom It May Concern,

My name is _______ and I'm contacting you on behalf of [brand], a microblogging platform and social networking website which allows users to post multimedia and other content to a short-form blog.

Through brand exclusivity, discounts and freebies, we aim to engage our target market and attract them to our e-commerce store, and we feel your venue is perfectly aligned geographically and functionally to fulfil this.

With this in mind, are there any renting vacancies available in June 2014? If so, could we please speak to a representative to submit our full business proposal?

Thank you for your time. I look forward to your prompt and favourable reply. If you have any questions regarding this enquiry please contact me at _____ or by email at contact@andrew.com
